The ‘Rude Boy’ singer - who is expected to be bridesmaid when the couple marry later this year - became friends with the singer and the comic separately, but admits she would never have predicted they would embark on a relationship together.

She said: “I met him a few years ago when he interviewed me, and became friends with Katy later, and it’s so funny because I would never have put the two of them together.

“But when she told me it made so much sense. I was like, ‘Of course you guys would be together, you are both just hilarious and rude and disrespectful, it’s perfect.’ ”

The Hollywood legend - who passed away yesterday (29.05.10) aged 74, due to complications caused by his prostate cancer - has been praised by numerous celebrities friends who are keen to pay their respects to the screen star.

Dennis’ ‘Easy Rider’ co-star Peter Fonda - who he also wrote the Oscar-nominated script with - admits he was “blessed” to know him.

Gary Coleman’s parents are desperate to know what happened to the actor before he died.

Sue and Willie Coleman - the estranged relatives of the ‘Diff’rent Strokes’ actor, who passed away on Friday night (28.05.10) after suffering from a brain haemorrhage and falling into a coma - are devastated they were unable to speak with the 42-year-old star before his passing and are anxious to know the circumstances surrounding his death.

Sue said: “We would’ve loved to have been there by his side at the hospital, to let him know we love him before he passed away. This is a shock to us. We loved Gary very much. We’re going to miss him.

“We’re not pointing fingers at anyone, but we need to know exactly what happened.

The singer-and-TV star and her rugby player fiance - who have children Ruby, two, and 16-month-old Dexter together - have apparently ended their romance after months of disagreements.

A source said: “It is an incredibly sad state of affairs. Both Gavin and Charlotte are deeply distraught. But after a lot of soul-searching, they realised this is the best course of action for them and the children. It was a mutual decision.

“To the outside world they were a golden couple. The truth is, they had the same insecurities as anyone else. Charlotte is very headstrong. In the end, Gav found it too much. He was blaming her for his rugby career stalling. She hated him going out drinking with mates.”

The ‘Gossip Girl’ actor never turns up to the set of the US drama wearing pants because he feels “more comfortable” without them, so raids the wardrobe of his character Chuck Bass if producers make him wear undergarments.

He stated: “I show up without it and have to put it on. I don’t usually wear underwear. It’s more comfortable and free to air it all out.”

The 22-year-old hunk - who has been dating co-star Jessica Szohr since 2008 - also admitted that despite working long hours, he is never too tired to have sex.
